Summary
Macimorelin causes a small QT prolongation, and ciprofloxacin also prolongs QT, so the combination may increase arrhythmia risk during the growth hormone stimulation test. The test is single-dose, which limits exposure.
What this interaction means in plain words
Ciprofloxacin and Macimorelin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Why it happens
Additive pharmacodynamic QT prolongation.
What to do
